Gum recession — the gradual pulling back of gum tissue to expose more of the tooth root — is surprisingly common and often goes unnoticed until it has progressed. Here is what you need to know.
Why Gum Recession Matters
Receding gums expose the sensitive root surface of your teeth, leading to sensitivity, increased risk of root decay, and eventually, if left untreated, tooth loss from loss of supporting bone. Gum recession is also aesthetically noticeable — teeth appear longer than they should and the gumline becomes uneven. Early identification and treatment prevents serious consequences.
Common Causes
The most common cause of gum recession is aggressive tooth brushing — brushing too hard or with a hard-bristled brush damages the gum tissue over time. Gum disease (periodontitis) is another major cause. Grinding or clenching the teeth, thin gum tissue, poorly positioned teeth, and even oral piercings can all contribute. Genetics also plays a role — some people are simply more prone to recession than others.
Signs of Gum Recession
Tooth sensitivity to hot, cold, sweet, or acidic foods and drinks is often the first noticeable sign. You may also notice that your teeth appear longer, see a notch near the gum line, or find that your gumline looks uneven. During a dental examination, your hygienist measures pocket depths and can identify early recession before it becomes symptomatic.
Treatment Options
Mild recession may be managed by addressing the underlying cause — switching to a soft-bristle brush, treating gum disease, or using a nightguard for grinding. More significant recession may require a gum graft procedure, where tissue is taken from the palate or a tissue bank and grafted to the receded area. This restores the gumline, reduces sensitivity, and protects the root surface. Pinhole surgical technique is a minimally invasive alternative for some patients.
